Title: Filter cleaning system - for filter used with continuous flow contg fine material esp air filter
Inventor: EDWARDS HAROLD ANTHONY
IPC: B01D46/00
Filed: 1971-11-26
Abstract: Esp used in cleaning air in TiO2 prodn plants, the filter bag hangs down from the dividing floor between the lower dirty air plenum and upper clean air plenum the cleaning unit consisting of a tube passed through the clean air plenum and entering the neck of the filter bag. This tube is closed at its lower end by a horizontal plate leaving a gap from the rim of the tube and with a central orifice. This orifice forms the principal outlet for the pulses of reversew flowing cleaning medium and the annular gap at the end of the tube forms a secondary outlet system such that a stagnant zone is formed in the filter during the flow pulses that hinders the flow of the air being purified in the forward direction, thus allowing the caked powder on the outside of the filter bag to be thoroughly broken up and dislodged by the main reverse flow through the principal orifice. Means are attached to the plate and tube to enable the width of the gap to be adjusted to suit the reverse flow pulse pressure.

Title: Electronic fuse for power amplifiers - has flip-flop with delayed reset turning off output stage transistors on overloading
Inventor: KIRKSAETER PER
IPC: H02H1/00
Filed: 1974-02-05
Abstract: The electronic fuse, for a power amplifier, as used in stereo equipment reduces the current flowing in the amplifier's output transistors to prevent overloading. A fast-acting flip-flop or trigger is coupled to the power amplifier's output stage and changes state when a given level is exceeded. This state-change turns off the power transistors for a given period of time. After this time has elapsed the flip-flop returns to its original state and the power transistors return to normal operation. The flip-flop's output is passed back to one of the amplifier's input stages.

Patent DE-2436090-A1 (DE)
Title: Rapid closing valve for steam power plant - has piston operated by pilot valve controlled by auxiliary valve
Inventor: KALB HANS
IPC: F01D17/14
Filed: 1974-07-24
Abstract: The valve head is normally pressed on the valve seat by a spring. The valve head houses a pilot valve and seat. High pressure steam is led through the pipe to the three-way auxiliary valve. When the main valve is closed this steam flows through the pipe into a space and through the clearance between the piston rod and guide into another space so that pressure is exerted on the valve head. Operating the auxiliary valve allows steam to flow out of the space allowing the pilot valve to open which in turn allows the pressure in the space to escape and allow the main valve to open.
